Patented Apr. 28, 1936 UNITED STATES PATENT OFFICE COMBINATION ROAD PARTING STRIP AND SEALING CAP Application December 8, 1934, Serial No. 756,627

2 Claims.

This invention relates to a combination road parting strip and sealing cap of the general type illustrated in my co-pending application Serial No. 725,431, filed May 14, 1934.

The object of the invention is to provide a more efiicient support for the sealing cap upon the parting strip whereby any tendency to puncture the seal will be ineffective.

Other objects Will appear hereinafter.

The preferred embodiment of the invention is iilustrated in the accompanying drawing in which:

Figure 1 is a perspective view of a portion of the combined parting strip and sealing cap;

Fig. 2 is a transverse vertical section of the same showing installation in a pavement; and

Fig. 3 is a plan view partly in transverse horizontal section on line 33 of Fig. 2 without the paving material.

The parting strip I is constructed of a single sheet of steel or other suitable material and is positioned on edge in use. It may. be of any suitable construction and is adapted to support dowel rods 2 which tie the sections 3 and 4 of concrete together at the joint.

The upper edge portion of the parting strip is provided with laterally pressed vertical beads 5 or the like as shown in Figures 2 and 3. Alternate beads extend in opposite directions. By reason of the beads 5 the upper edge of the parting strip has a widened surface for receiving the sealing cap 6.

The sealing cap 6 is constructed of sheet copper or other suitable non-corrodible ductile metal. The cap 6 has a central expansible section I which extends downwardly over the top of the parting strip I. The side edges of the cap 6 constitute lateral flanges 8 which are embedded in the respective concrete sections 3 and 4 of the pavement.

The expansible section I has a flat top 9 adapted to rest on the top edge of the parting strip to support the sealing cap, and downwardly depending side walls III which are crimped inwardly near the top at H to contact with the parting strip. The side walls ID are curved, both above and below the crimped portion l l to provide additional flexibility, and are preferably spaced from the parting strip at all points except at II.

The curved side walls provide for flexing irrespective of the relative position of the parting strip and cap and any tendency of the parting strip to raise relative to the cap will not puncture the top 9, by reason of the wider contact between the two and also by reason of the flexing of the curved side walls of the cap.

Various embodiments may be employed within the scope of the accompanying claims.

I claim:

1. A joint for pavements and. the like comprising a parting strip of sheet metal positioned on edge between two horizontal pavement slabs, and a seal of non-co-rrodible sheet metal having side edges embedded in the respective pavement slabs and having an upwardly extending central expansible fold, said expansible fold having a substantially flat top of substantial width resting upon the upper edge of said parting strip, and said parting strip having its upper edge formed to provide a bearing support for said seal of greater width than the thickness of said strip.

2. A joint for pavements and the like comprising a parting strip of sheet metal positioned on edge between two horizontal pavement slabs, and a seal of non-corrodible sheet metal having side edges embedded in the respective pavement slabs and having an upwardly extending central expansible fold, said expansible fold having a flat top of substantial width resting upon the upper edge of said parting strip, and said parting strip having vertical ribs formed in its upper edge to provide a bearing support for said seal of greater width than the thickness of said strip.
